The Cerebral Enhance-O-Tron is an invention made by Calvin. Its purpose was to enhance one's brain. It was used to enhance Calvin's brain when he was writing a report about Tyrannosaurus Rex being a "fearsome predator" or a "loathsome scavenger". The effects might wear off when the user goes off task, as he says he will make illustrations of a T-Rex eating people in the Natural History Museum before writing the report thus going off task and returning to normal.
